Find, to the nearest tenth of a centimeter, the length of a diagonal of a square if the measure of one side is 8.0 centimeters.

  • Geometry -

    Pythagorean Theorem

    a^2 + b^2 = c^2

    8^2 + 8^2 = c^2

    64 + 64 = c^2

    11.3 = c

    The diagonal of a square measures 12 feet.
    a. What is the exact measure of a side of the square?
    b. What is the area of the square

  • Geometry -

    Use the Pythagorean Theorem.

    What do you get for the measurement of a side of the square?

  • Geometry -

    I manage to get X^2+X^2=144

  • Geometry -

    Right so far.

    2x^2 = 144
    x^2 = 72
    x = 8.4852813

    Each side = 8.4852813 feet

    A = s^2
    A = 72 square feet
